Abstract: Atomic force microscopy (AFM) is one of the most effective tools in nanotechnology researches. Using the raster scanning method with a soft cantilever, three dimensional sample surface topography can be obtained with a ...

Abstract: To understand the physics behind dropwise condensation, a microscopy technique must be able to measure a sub-nanometer film at a high temporal resolution (>1,000 FPS). In this work, automated Surface Plasmon Resonance ...

Abstract: For occurring dropwise condensation, the droplet growth behavior such as single droplet growth, coalescence, and falloff of large droplets play a major role in regard to condensation heat transfer and water harvesting. The ...

Abstract: This study aims to experimentally examine rebounding characteristics of a freefall droplet which impacts on a static droplet with a sphericalcap shape in a low Weber number range. Two wellaligned highspeed cameras were ...

Abstract: Opto-microfluidic methods have advantages for manufacturing complex shapes or structures of micro particles/hydrogels. Most of these microfluidic devices are made of polydimethylsiloxane (PDMS) by soft lithography because ...

Abstract: The main objective of this study is to examine the frosting characteristics affected by the surface wettability. Two different copper surfaces – bare and nano structured were prepared for the experiments. Their static ...

Abstract: A surface plasmon resonance (SPR) imaging microscopy coupled to a high-speed camera is used to visualize the frost propagation inside a subcooled liquid droplet. The SPR experimental setup consists of a 50 nm thick gold-coated ...

Abstract: Neutron imaging enables direct visualization of evaporation and condensation of cryogenic propellants in metal containers such as aluminum and stainless steel. CFD models of propellant behaviors inside the large tanks have ...
